V = 25,364.4 cm^3 Is volume
r = 2.7g/cm^3 Is density
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.
m = 68,486,6 g is the answer.
